This invention has relation to window sun shades and refers particularlyto improvements in ventilating roller shades.

The general object of the invention is the provision of a roller shadeof simple and inexpensive construction, which is capable of arrestingsunlight and at the same time to admit an abundant supply of air. Withthis object in view my invention consists in the combinationshereinafter fully described and illustrated in the accompanying drawing,of which: v

Fig. 1 illustrates a ventilatingroller shade embodying the invention, 1

Fig. 2 is across sectional end elevation of the structure, and v Fig. 3shows a modified form of device,

The structure of my invention comprises a shade roller 1 of any wellknown standard construction, to which two rows of overlapping strips ofshade cloth 2, 3 are attached. These strips may all be alike. The strips3 are first mounted on. the roller in uniform spaced relation, whereuponthe strips 2 are fastened on top of the former in similar spacedrelation but so that each strip 2 covers a space between two ofthestrips 3. V

A spreader bart is placed between the two rows of strips in closeproximity to the roller, and this bar may conveniently be hung on thepivots of the shade roller, substantially as indicated in the drawing,or it may, of course, be mounted on the windowframesupporting theroller, in the proper relation thereto. .The lower ends ofthe strips arefastened to a suitable cross bar 5 in any convenient manner.

The spreader bar 4: and the bottom bar 5are preferably made thesamewidth and may be as wide as the roller so as to aiford ample spacebetween the two rows of strips.

The width of the strips in relation to the widtlrof the openings,betweenthe strips should be so proportionedthat no slanting ray ofsunlight may pass through the openings of the two rows. As the two rowsof strips are shown in Fig. 1 such rays may pass through the space6and'the space 7, but this is done merely for. the sake of clearness ofillustration. In actual practice, where itis'desired to cut out sun raysentirely, the opensae. seal No. 366,244.

ings between all thestrips must be so narrow relative to the width ofthestrips that this cannot ha'ppen. 1 The structure of Fig. 3 comprisestwoshade rollers 10,11, one mounted directly abovethe other and eachcarryingone row of strips 12, 13; The rollers and stripsmay all "bealike, the only dilference'between the two being, that the strips on'onerollerare mounted clockwise and on the other anticlockwise, whereby aneffect isproducdsimilartothat above described. Inthis case nospreaclerbar is re quired, but as an extra roller with its mountings isneeded; this structure is,perhaps, not

as inexpensiveias the one above described. y 'lheadvaiitage of thismodified device is that each of the shades maybe operated independent ofthe other. In case more light is desired, the one may be lowered morethan the other. Also that one maybe replaced without disturbing theother.

Because of the many different widths of windows it is common practice totrim the sideedges of the shade cloth to the size desired, leaving suchtrimmed edges unpro--:

'tected and apt to unravel. WVith my device it is possible to carrystrips of standard sizes and, where there is a variation of a few inchesin the Width of the shades, to vary the space between the stripsslightly. If, for example, a one-yard shadeis required, four six-inchstrips may be employed in each .row with three-inch spacing between thestrips, and one three-inch space at one end of each row. Should now athirty four inch shade 1 be required, it is only necessary to reduceeach space by one-half inch, all the strips remaining the same.

m OF

It is also possible with my device to use i strips of different colorsand ornamentations,

andtherfeby to provide a great number of desirable decorative eifectsnot obtainable in ordinary shades without incurring great expense.

Iclaim:

v 1. In a sunshade device, tworows of strips of shade cloth, each ofwhich is fastened to a roller of the device at one end and to a 1 apartand so related that the strips of one row cover and overlap the spacesbet-ween. the strips of the other row, and means maintaining one roWspaced apart from the'other row.

2. The combination with a shade roller, of a row of shade cloth stripsmounted on said roller and uniformly spaced thereon, a second row ofstrips mounted on the roller to cover the spaces between the strips ofthe first row, means mounted'close'to the roller for maintaining the tworows of strips spread apart, and a cross member to which the free endsof the strips are fastened, the strips of the two rows being bent aroundsaid mem-f her from opposite sides.

3. The combination With a shade roller, of two rows of shade clothstrips mounted on said roller, the strips of one-row covering andoverlapping the spaces between the strips of the other row, a memberhung on thepivots of the roller and capable of maintaining the two rowsspread apart, and a member to Which the free ends of both rows of stripsare fastened from opposite sides.

, 4. In a roller shade, two rows of shade cloth strips forming twobarred curtains positioned one behind the other, the strips of'onecurtain covering the spaces between the strips of the other curtain,meansonwhich said curtains are Wound for raising andlo wering,

and means maintaining the two curtains spaced apart. 7 I In testimony'whereof I have hereunto affixed my signature. 7 JOHN HEALD.
